Just as one classic novel-turned-musical-turned- movie bids adieu to the spotlight (and Anne Hathaway’s hair), the next one is waiting in the wings. The national tour of “Jekyll & Hyde” visits Des Moines next week on its way to Broadway in April and, most likely, a Hollywood studio within the next year. The producer, Mike Medavoy (“Black Swan”), and a partner bought the movie rights last month.

So if Robert Louis Stevenson’s 1886 tale follows the path of Victor Hugo’s, from 1862, we just might see the good doctor and his evil alter ego fight over whom to thank at the 2015 Oscars.

Meantime, in the version that opens Tuesday at the Des Moines Civic Center, both title roles belong to Constantine Maroulis, the shaggy former “American Idol” finalist who starred in the “Rock of Ages” tour that came here two years ago. His co-star is the R&B diva Deborah Cox, who, like Hathaway, plays a hooker with a heart of gold.

Turns out “Les Miz,” which marched into the Civic Center in October, was the first musical Cox ever saw.

“I was probably 10 or 11, and it just blew my mind,” said the multi-platinum recording star, who grew up in Toronto. “I’d never actually seen a musical with a full production and lighting and sets and costumes. I’d never seen anything like it.”

She made a name for herself in pop music, singing with the likes of Whitney Houston and Celine Dion, and made her Broadway debut in 2004 in Elton John and Tim Rice’s “Aida.”

But that wasn’t quite like Lucy Harris, the prostitute Dr. Henry Jekyll meets during a night on the town.

“She’s a survivor,” Cox said. “She’s a hustler and a woman that just doesn’t take any crap ... but she has her own demons, as well.”

The musical, with a book and lyrics by Leslie Bricusse and music by Frank Wildhorn, first hit the stage 23 years ago and had a respectable three-and-a-half-year run on Broadway in the late ’90s. Hollywood has produced more than a dozen versions of its own, including one that starred Spencer Tracy that was nominated for three Oscars in 1942. Another, called “Dr. Jekyll and Ms. Hyde,” was up for three not-so-prestigious Razzies in 1996.

Neither movie won an award, but the next version just might. The right cast could show the rest of the world what loyal “Jekkies” have been saying all along.

“It really resonates with people because everyone has their dark side or their vices to deal with,” Cox said. “It’s an ongoing battle that never goes away.”
